Try loading Minecraft without mods, and if it doesn't work post the crash report. This looks like it has something to do with Optifine?

I don't think it is entirely, one part said
"SCHWERWIEGEND: Unable to launch java.lang.ClassNotFoundException: net.minecraft.client.main.Main at net.minecraft.launchwrapper.LaunchClassLoader.findClass(LaunchClassLoader.java:179)"
and
"Caused by: java.lang.NullPointerException"
One part probably was unable to launch the ClassNotFoundException, at the (launchwrapper) and was caused by a null pointer exception.
This showed a question about what NullPointerException, and one answer showed what it is. I would usually think those are caused by bugs
